Problems solved by technology

Zinc-containing anti-wear hydraulic oil can easily pass through the vane pump, but it is difficult to pass through the plunger pump, because the ZDDP in the formula will cause severe corrosion to the copper-plated parts of the high-pressure plunger in use, resulting in damage to the hydraulic pump, and when the oil is mixed with Severe emulsification occurs after a small amount of water, causing blockage of the filter system

Abstract

The invention discloses a high-viscosity high-pressure antiwear hydraulic oil which is prepared from the following raw materials in parts by weight: 30-50 parts of base oil, 8-16 parts of diisodecyl sebacate, 4-8 parts of polymethacrylate (PMA), 3-9 parts of dustless dithiophosphate, 2-14 parts of thiadiazole derivative, 3-6 parts of arylamine antioxidant, 1-6 parts of sulfonate, 2-4 parts of high-base-number sulfurized calcium alkyl phenate, 6-12 parts of vulcanized isobutylene, 2-8 parts of pentaerythritol ester, 7-10 parts of vulcanized isobutylene, 2-4 parts of di-n-butyl phosphite and 1-6 parts of di-tert-butyl-para-cresol. The high-viscosity high-pressure antiwear hydraulic oil has the advantages of favorable demulsibility, favorable hydrolytic stability, favorable heat stability, favorable filterability, outstanding wear resistance and obvious energy-saving effect.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil, in particular to a high-viscosity high-pressure anti-wear hydraulic oil. Background technique [0002] At present, my country's industrial modernization process is accelerating, and the awareness of environmental protection in the whole society is gradually increasing.
